Disulfides are compounds that have S— S bonds, like peroxideshave O— O bonds. Thiols are organic compoundsthat have the general formula R— SH, where R is a generichydrocarbon. The SH- ion is the sulfur counterpart ofhydroxide, OH-. Two thiols can react to make a disulfide,R— S— S— R. (a) What is the oxidation state of sulfur ina thiol? (b) What is the oxidation state of sulfur in a disulfide?(c) If you react two thiols to make a disulfide, are youoxidizing or reducing the thiols? (d) If you wanted to converta disulfide to two thiols, should you add a reducingagent or oxidizing agent to the solution? (e) Suggest whathappens to the H’s in the thiols when they form disulfides.
